8.2.2.2.2 Inductor Selection (L1)
- Calculate the inductor Volt ? microsecond constant, E ? T (V ? μs), from Equation 9:
Equation 9.
Calculate E ? T (V ? μs)
Equation 10.
- Use the E ? T value from the previous formula and match it with the E ? T number on the vertical axis of the Inductor value selection guide shown in Figure 8-8.
E ? T = 115 V ? μs
- On the horizontal axis, select the maximum load current.
ILOAD(Max) = 3 A
- Identify the inductance region intersected by the E ? T value and the maximum load current value, and note the inductor code for that region.
Inductance Region = H150
- Identify the inductor value from the inductor code, and select an appropriate inductor from the table shown in Table 8-4. Part numbers are listed for three inductor manufacturers. The inductor chosen must be rated for operation at the LM2576 switching frequency (52 kHz) and for a current rating of 1.15 × ILOAD. For additional inductor information, see Section 8.1.2.
Inductor Value = 150 μH
Choose from AIE part #415-0936, Pulse Engineering part #PE-531115, or Renco part #RL2445.
